1 Obviously, 'bypturning" the handle 4,] the are employed withcomparatively thin doors, such as used forsteel lockers for example,

much difiiculty isfound in providing a' comparatively simple-"andinexpensive yet cffec-tive and durable locking device to lock the locing devices in the'door locking position, but by-my improvementhereinafter do: s'cribed,, I have been "able: to provide such alockingrneans which I have found satisfies all conditionsin' a most'efl'ectivemanner.

'l lB-representswhat I will term the'lat'oh looking member; Inthepreferred form this member l l'is hollowed out, by being struck up fromsheet metal,fso as to provide a rounded locking @115 which forms alock"' ing abtitment. One side of the member 1,4:

' is'fiattened as at 16 to provide clearance for the latch hub when thedoor is to be unhub :ofthe-latch member 2 is cut away, prefera bly on anarc, and as shown is provided with an -up-turned lip 17 which forms abroad bearing-faces The latch locking member'14c is mounted onthe innerend of a key controlled-rotatable plug 18, the end of said plug beingsquared or slabbed ofi', 'for' example as-shown in.Fig..5, so as'toproject into a c'entralpassage inthelocking member j 14.; Thispassage isprovided with one or more stop shoulders 19 19 (Fig.- .7) ,whereby theend of the plug 18-maypartake of a d( ee'Fig-'2)" The rearside of the 7Y limited free rotary movement beforeit starts tovturn the lockingmembernll. The. plug 1 8-may :be the usual key-plug suchgas round I fin, a pin cylinder lock whereby: the same may be operated byithe usualflat} key designed toractuatepin tumbler s'. :'20 represents thecylinderwportion ofthepin cylinder .lock which may .be provided withoffsets 21%21, wherebytheeylinder maybe securelyrivted tQi'zi he-lidecofythe door; 1,5; 22 is. Ia i oiist no i from the cylinder 20 inwhich the usual pin tumblers or followers are located, which offsetin.this particular instance performs an a dditionali-function, namely,. thefunction of a stop to limit the turning movement of the latch lockingmember 14. On the inside of the latch locking member are two lugs 'henthe-member 14 isturnedin one direction the lug 23.,will.strike againstthe offset 22 and check the further rotation of the memberliin, thatdirection, at which timethe squared end .of theplug 18 will bear againstone of theshoulders l9 and willbe causedtostop in a position to permitthe key to be withdrawn .orinserted. When the plug 18 .is turnedinanopposite direction, it'will turnidly for about one-quarter. of a turn\whereupon the squared-end iwill-,pick up the shoulders-muse that thecontinued rotation of the plug by the keywill rotate the member. 14until the other lug 24-Sl11'lk against. theaopposite side of the stop22-at \vhichtimethe key-.plugwill again be positioned .so that. the key,may be-withdrawn orinserted. '.Theqmember -14 may be held on theendofthe plug by any suitable-means, such as a. washer .25 and .a pin26 .Theoperation of the device is asfollows: Then the -parts. stand, asshowninFig.1, the ,door locking devices 2, 5,.6arein position to lock the. doorclosed, (-andi-the ;latch locking-member. likeWisestands .in a .positionto prevent the .opening of the door locking devices, that is ,to say,the locking device 14 .is projected ,against,or.close to, the rear sideof the hub ,of the latch so that anysattempt toturnthe hub will beblocked by theengagement of. one or the other end of the abutment 17,against the adjacent, part of the member 14. If a key is inserted. inthe plug of the locl; and turnedin. a counterclockwise direction (asviewed in; Fig. 1), the plug will partake of a free movementformic-quarter of a,rotation, at which time the squared end of the'plug'will pick up the shoulders 19 .so that a'continued' rotation ofhe-plug for three-quarters of a turnwill cause a corresponding turningmovement of themember 14 leaving itfinally in theposition indicatedin-Fig. 2, wherein the-key maybe removed. In the first position shown inFig.1, the lug23 bearsagainst one side of thestationarycoifset 22.TllVhen,however, the member :14 has-been turned tothe position showniin'Fig. 2, the .lug 24: will be brought to and againstthe-opposite side ofthe offset 22 thusstopping the turning movement .of the member 14' inthe'position shown in Fig.2 inxwhichithelsqu'ared ofi side of theniember1 L lies to the rear of the' hub of the latch 2 ..so. that the lattermayxbefreely turned by the handle @f'for the purpose of opening Candiclosingthe door 1. I I, I Eromlthe foregoing, it] is apparent thattheflooking means is" of an -exceedingly-'simple character all the partsof which may be economically produced and easily assembled,

and iyet when assembled -said devices I afford a maximum degree of.security. Il'rWill also be observed that there is comparatively nothingto get out of order and to require hold. theslocking member lat on theplug in such a way that there is no lost motion or capacity forindependent relativev movement and-to that endslmay provide in some'instanees,.a,locking member snehas indicated at 14?,Fjgs 8, in which thecentral opening through which the irregular. end of the, plug18%passesis shaped to said'lirregular end. or otherwise connectedtherewith, so thatthere will beno free movement.

.I- thewpreferred construction the lock ng member ,16' is drawn up: froma single; piece of 131. 8%; metalwithv the rearwardly flanged edgeintegralawith .the face so that; it will furnishjnot 1 only. a broadbearing 7 face for engagement with ,the hub abutment shoulderswhenthedoor; isoto be: locked, but will withstand efl ectivelyl heavypressure. :While I-have shown .and described the preferred form of myimproved locking means, it should, of course, beunderstood that variousmodifications in the particular design, construction, and arrangement:of parts may be resorted to Without departure from" the spirit-iandscopeof my invention.
